For adjustment of precise mitre angles, the base plate has
adjustment notches on the left and right at 0° and 45°. Swivel
the base plate 4 to the desired position according to the scale
13. Other mitre angles can be adjusted using a protractor.
Afterwards, push the base plate 4 to the stop toward the
mains cable.
Push the assembly plate with the guide roller 5 forwards until
it faces against the back of the saw blade and tighten the
screws 12 again.
The splinter guard 11 can not be inserted for mitre cuts.
Offsetting the Base Plate (see figure D)
For sawing close to edges, the base plate 4 can be offset to
the rear.
Completely unscrew the screws 12.
Lift the base plate 4 off and offset it in such a manner that the
front screw 12 can be screwed into the rear bolt hole 14. The
second screw 12 is not required for sawing with the base
plate offset.
Push the base plate 4 toward the positioning pin/mark 15 un-
til it engages and slide the assembly plate with the guide roller
5 forwards against the saw blade back. Then tighten the
screw 12.
Sawing with the base plate 4 offset is possible only with a mi-
tre angle of 0°. In addition, the parallel guide with circle cutter
18 (accessory) as well as the splinter guard 11 may not be
used.

Starting Operation

 Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
Switching On and Off
To start the machine, press the On/Off switch 2 and keep it
pressed.
To lock the pressed On/Off switch 2, push the lock-on button
1 toward the right or left.
To switch off the machine, release the On/Off switch 2. When
the On/Off switch 2 is locked, press it first and then release it.
Controlling/Presetting the Stroke Rate
(GST 65 E/GST 65 BE)
Increasing or reducing the pressure on the On/Off switch 2
enables stepless stroke-rate control of the switched-on
machine.
Light pressure on the On/Off switch 2 results in a low stroke
rate. Increasing the pressure also increases the stroke rate.
When the On/Off switch 2 is locked, it is not possible to re-
duce the stroke rate.
With the thumbwheel for stroke rate preselection 3, the
stroke rate can be preset and changed during operation.
The required stroke rate is dependent on the material and the
working conditions and can be determined by a practical trial.
Reducing the stroke rate is recommended when the saw
blade engages in the material as well as when sawing plastic
and aluminium.
1 609 92A 2WC | (10.11.16)
After longer periods of work at low stroke rate, the machine
can heat up considerably. Remove the saw blade from the ma-
chine and allow the machine to cool down by running it for ap-
prox. 3 minutes at maximum stroke rate.

Working Advice

 Before any work on the machine itself, pull the mains
plug.
 When working small or thin work pieces, always use a
sturdy support or a saw table (accessory).
Check wood, press boards, building materials, etc. for foreign
objects such as nails, screws or similar, and remove them, if
required.
Plunge Cutting (see figure E)
 The plunge cutting procedure is only suitable for treat-
ing soft materials such as wood, plaster board or simi-
lar! Do not work metal materials with the plunge cut-
ting procedure!
Use only short saw blades for plunge cutting. Plunge cutting is
possible only with the mitre angle set at 0°.
Place the machine with the front edge of the base plate 4 on
to the workpiece without the saw blade 6 touching the work-
piece and switch on. For machines with stroke rate control,
select the maximum stroke rate. Firmly hold the machine
against the workpiece and by tilting the machine, slowly
plunge the saw blade into the workpiece.
When the base plate 4 fully lays on the workpiece, continue
sawing along the desired cutting line.
Parallel Guide with Circle Cutter (Accessory)
For cuts using the parallel guide with circle cutter 18 (acces-
sory), the thickness of the material must not exceed a maxi-
mum of 30 mm.
Parallel Cuts (see figure F): Loosen the locking screw 17 and
slide the scale of the parallel guide through the lead 16 in the
base plate. Set the desired cutting width as the scale value on
the inside edge of the base plate. Tighten the locking screw 17.
Circular Cuts (see figure G): Set the locking screw 17 to the
other side of the parallel guide. Slide the scale of the parallel
guide through the lead 16 in the base plate. Drill a hole in the
workpiece centred in the section to be sawn. Insert the centring
tip 19 through the inside opening of the parallel guide and into
the drilled hole. Set the radius as the scale value on the inside
edge of the base plate. Tighten the locking screw 17.
Coolant/Lubricant
When sawing metal, coolant/lubricant should be applied
alongside cutting line because of the material heating up.

Maintenance and Cleaning

 Before any work on the machine itself, pull the mains
plug.
 For safe and proper working, always keep the machine
and ventilation slots clean.
